To obtain an OAuthClientId, OAuthClientSecret, CallbackURL, and you first need to create an app linked to your Oracle Eloqua account.

Create and Configure a Custom OAuth App

You can follow the procedure below to obtain the client credentials, the client Id (app Id) and client secret:

1. Log in to Oracle Eloqua.
2. Click Settings -> AppCloud Developer (under Platform Extensions) -> Create New App.
3. Enter a name, icon, and description for the app to be displayed to users when they connect to Oracle Eloqua. The OAuthClientId and OAuthClientSecret will be displayed.
4. Set the CallbackURL to http://localhost:3000, or another port of your choice.

5. If you are creating a desktop application, set the CallbackURL to http://localhost:3000, or another port of your choice.

   If you are creating a Web application, set the Callback URL to a page on your Web app you would like the user to be returned to after the user has authorized your application. Note that Eloqua requires that the Callback URL begins with https://. You must specify a port.

When you connect the add-in opens the OAuth endpoint in your default browser. Log in and grant permissions to the application.
